Abstract: PROBLEM TO BE SOLVED: To obtain a homodyne radio receiver using a low intermediate frequency for an orthogonal signal by demodulating an applied signal by means of a specified frequency and recovering an IF signal corresponding to a base band signal which is demodulated by means of the specified frequency. SOLUTION: The outputs of demodulators 70 and 75 are respectively supplied to elements 80 and 85. In them, input signals are multiplied by Wi and results are integrated over one signal period.

Filed: 1990-10-22
Abstract: PURPOSE:To obtain an automatic focal point adjusting device which can determine the direction and distance of the focal point position by one detection by using a micro-prism for an optical system, and performing the calculation by intensity projection. CONSTITUTION:A TFT liquid crystal display substrate 11 has many wiring patterns vertically and horizontally, and they are photographed by an image pickup section 2 via an optical device 1. When the focal point position is located on the front side of the image pickup section 2, no image is correctly formed on a micro-prism 1b, the edge of the wiring portion 11b of the pickup image is made vague, and a triangular pattern due to the prism shape of the prism 1b appears in the direction shown in the figure. The direction of the pattern is recognized via the image processing by a controller 7 to judge the front side position. A disturbance due to linear integration occurs on the calculation result via the intensity projection of the image, and the width of the pattern including the disturbance portion becomes wide. The pattern width W1 is detected and compared with the known W0 to determine the distance to the focal point position. The focal point is adjusted via a focal point adjustment section 1d. Focal point adjustment is performed correctly and quickly.
